Step 1 Heat the oven to 375 degrees. In a medium saucepan, combine the ginger, sugar and wine. Bring to a boil, stirring to dissolve the sugar. Reduce the heat and simmer until the syrup is reduced to 3 tablespoons. Add the broth and bring to a boil, stirring.
Step 2 Meanwhile, peel, halve and core the pears. Arrange, cut sides down, in a single layer in a large buttered baking dish. Sprinkle with half of the lemon juice. Pour the syrup over the pears.
Step 3Bake, uncovered, until golden brown and glazed, about 45 minutes. Baste often with the syrupy juices. Sprinkle with the remaining lemon juice. If not used at once, set aside at room temperature for up to 8 hours and reheat gently before serving; do not refrigerate.
